All observational data as well as metadata was obtained from the Bureau of Meteorology. The 38 recording stations considered were in the most part staffed by Bureau of Meteorology officers. To isolate the issue of anemometer replacement, only observing stations located at airports (i.e. those with consistent exposure) and with more than 30 years of record were considered. The visual inspection of the observed daily peak gust wind speed time-series for most of the Bureau of Meteorology observing sites considered in this study is sufficient to indicate that in general the early part of the observing record contains a higher frequency of extreme events, and also the largest amplitude extreme events.
Statistical analysis of the daily maximum gust wind speed observations was conducted by employing extreme value distributions (EVD) to examine the difference between two datasets:
(1) time-series of Dines & cup anemometer observations (no overlap for each station)
(2) coincident Dines & cup anemometer observationsCommonwealth of Australia (Geoscience Australia)ownerCommonwealth of Australia (Geoscience Australia)Manager Client Services02 6249 9966Cnr Jerrabomberra Ave and Hindmarsh Dr GPO Box 378CanberraACT2601Australiaclientservices@ga.gov.aucustodianunknownunknownunknownGA PublicationRecordwindthemeEarth SciencesAustralian and New Zealand Standard Research Classification (ANZSRC)2008-03-31T00:00:00+11:00publicationAustralian Bureau of Statistics (ABS)http://www.abs.gov.au/ausstats/abs@.nsf/Latestproducts/1297.0Main%20Features32008?opendocument&tabname=Summary&prodno=1297.0&issue=2008&num=&view=owner9780642483584licenselicenseCreative Commons Attribution 4.0 International Licenceunclassifiedengutf8geoscientificInformationunknown96.0168.0-44.0-9.0Commonwealth of Australia (Geoscience Australia)02 6249 9966Cnr Jerrabomberra Ave and Hindmarsh DrGPO Box 378CanberraACT2601Australiasales@ga.gov.audistributor2012-06-06T00:06:00onLinehttps://d28rz98at9flks.cloudfront.net/71858/Rec2011_023.pdfFile downloadRecord (pdf)downloadnonGeographicDatasetGA PublicationUnknownSource data not available.unclassified
